A fairly straightforward way is to use nested loops:

>>> for l in ltrs[0]:
...   for j in ltrs[1]:
...     for k in ltrs[2]:
...       print l,j,k

A C F
A C G
A C H
A C I
A D F
A D G
A D H
A D I
A E F
A E G
A E H
A E I
B C F
B C G
B C H
B C I
B D F
B D G
B D H
B D I
B E F
B E G
B E H
B E I


Not the most elegant, but probably the easiest to follow.
